Analysis of hypertension morbidity and influencing factors among rural residents in Chongqing city

Objective To understand the hypertension morbidity and influencing factors among rural residents in Chongqing city and to provide the basis for preventing and controlling hypertension. Methods Rural residents sampled by the multiple stratified cluster random sampling method were investigated with questionnaire and physical examination. The differences of hypertension morbidity among residents with different age, education levels, smoking and drinking behaviors were examined with Chi-square test. The dependent influencing factors of hypertension morbidity were assessed by multivariable logistic regression. Results The subjects of present study were 1 528 residents [average age:(51.3±13.9) years old]. The crude and adjusted morbidities of hypertension were 39.80% and 28.4%, respectively. The smoking rate at present was 22.51%. The drinking rate in the past 12months was 17.54%. The fruit intake in 82.98% residents was less than one time each day. The rate of milk intake was 21.47%.The rate of pickle intake was 69.63%. The proportion of residents with high or middle physical activity was 9.23 %. The proportion of residents with obesity was 9.29%. The multi-variable logistic regression indicated that age, intake of soy products, the family history of hypertension and weight were the independent influencing factors for hypertension morbidity. The OR values were 1.99(95%CI: 1.70-2.32), 1.31(95%CI: 1.03-1.68), 1.00(95%CI: 1.00-1.01) and 1.96(95%CI: 1.65-2.34), respectively. Conclusion The morbidities of hypertension and obesity among rural residents are high. Smoking, drinking, unreasonable diet and lack of physical activity are the risk factors of hypertension. It is urgent to strengthen the prevention and control of hypertension.
